Abstract
Systems, methods, assemblies, and devices for providing a subsea module with a resident valve arrangement and one or more retrievable modules. One or more valves of the resident valve arrangement may be adjusted to provide a cleaning fluid path to clean an individual retrievable module without cleaning the entire manifold or other retrievable modules.

1-7. (canceled)
A subsea system comprising:
- a subsea manifold comprising:
- a production header line;
- a gas lift header line;
- a test production header line;
- and
- a resident valve arrangement disposed in a permanent portion of the subsea manifold, the resident valve arrangement comprising a plurality of header selection valves;
- and
- a plurality of retrievable modules removably disposed in the subsea manifold, each retrievable module of the plurality of retrievable modules comprising:
- one or more flow meters;
- one or more flow chokes;
- and
- a plurality of fluid connections to a respective plurality of flow lines of the subsea manifold, the plurality of fluid connections fluidly coupled to a respective plurality of header selection valves that are resident to the permanent portion of the subsea manifold.
